Conversation
LynoBridge addresses the absence of a direct EVM L2 entry point into the Canton Network. Today, users must interact with Ethereum mainnet manually to bring assets into Canton. LynoBridge eliminates this friction by enabling any liquid EVM token on supported L2 networks to be transferred as USDCx to Canton, with Ethereum mainnet transit handled automatically at the protocol level via Circle CCTP and Relay Link integration. The proposal covers three milestones: bridge launch with embedded non-custodial wallet and Canton Wallet SDK integration, DEX/swap with a DAML-based sharded AMM using constant product formula and professional security audit, and staking and lending primitives with utilization-based interest rate model and a second audit engagement. All DAML contracts published under Apache 2.0. Implementation is built on Canton Ledger API and xReserve. Signed-off-by: moscowxy <160858163+moscowxy@users.noreply.github.com>

Summary
LynoBridge connects EVM-compatible Layer 2 networks directly to the Canton Network, enabling any liquid EVM token to be transferred as USDCx without manual Ethereum mainnet interaction. The proposal covers bridge launch, DEX/swap with security audit, and staking and lending primitives, with all DAML contracts published under Apache 2.0.
Checklist
/proposals/Notes for Reviewers
LynoBridge is an active Canton mainnet validator with Provider status. A closed DevNet simulation produced 850+ bridge transactions in 3 days, and bridge transactions are currently operational on Canton mainnet. A live demo or video is available upon request.
The implementation is built on Circle CCTP and Relay Link for EVM-side token conversion, Canton Ledger API for party provisioning and command submission, Canton Wallet SDK for the embedded non-custodial wallet, and xReserve for USDCx minting. DEX contracts use a sharded AMM architecture with constant product formula to mitigate contention under Canton's contract consumption model. All DAML contracts will be published under Apache 2.0. Happy to answer any questions on architecture or implementation details.
